Photosynthesis

  • Reactants: Water, Carbon Dioxide, Light Energy
  • Products: Oxygen & Glucose

  • Light Reactions split water and produce NADPH and ATP
  • Calvin Cycle synthesizes glucose from carbon in CO2

Calvin Cycle

  1. RuBisCo incorporates carbon from CO2 into organic molecule
  2. Molecule reduced (gains e-) by ATP & NADPH
  3. RuBP regenerated

6 Turns of cycle for 6-carbon glucose

Elements of a Storyboard

  • Shot images: Individual panels featuring 2D drawings to show what’s happening—actions, characters—throughout a video
  • Shot number: The number indicating when a shot appears according to a video’s shot list
  • Action: The primary activity happening in a shot
  • Dialogue or narration: Any speech that is heard throughout a video
  • FX: Any additional technical details that explain how the shot is created (e.g. camera angles, camera movement, sound effects, special effects)

Gallery Walk

  • Set up your materials for other students to view
  • If you have a specific question to guide feedback, write it on blue paper
  • Use sticky notes to comment on other groups’ work – What you like, how they can improve, clarifying questions
